Date: Tue, 04 Nov 2008 20:26:03 +0000 Message-ID: <87y6zz5jc4.fsf@oxford.xeocode.com> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Return-path: Sender: linux-raid-owner@vger.kernel.org To: linux-raid@vger.kernel.org List-Id: linux-raid.ids # mdadm --create /dev/md0 --level 0 --raid-devices 60 `cat drives` mdadm: invalid number of raid devices: 60 # mdadm --create /dev/md0 --level 0 --raid-devices 32 `cat drives` mdadm: invalid number of raid devices: 32 # mdadm --create /dev/md0 --level 0 --raid-devices 33 `cat drives` mdadm: invalid number of raid devices: 33 Firstly, "invalid number" is a terrible error message. 60 is a perfectly good number. The error message gives no indication of why it doesn't find 60 to be a "valid" number. Secondly there's no mention in any documentation for mdadm or anywhere else that I can find of any arbitrary maximum number of drives. Thirdly, WTF?! -- greg
